[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fishing rod formed by connecting a plurality of rods, in particular, a main rod and an upper rod connected to the tip of the rod are connected in a swing-out manner, and the positional relationship of these is adjusted by adjusting the positional relationship between them. The present invention relates to a fishing rod whose length can be adjusted.
[0002]
[Prior art]
In a conventional fishing rod, a plurality of cylindrical rods can be sequentially inserted from the tip-side rod into the rod-side rod. When fishing, each chassis is pulled out to the tip side sequentially and fitted and fixed to be used as a single chassis. On the other hand, at the time of storage, the body on the tip side is sequentially stored in the body on the base side to make it compact.
[0003]
Further, some conventional fishing rods have been devised so that fishing can be performed by adjusting the positional relationship between the former rod and the former rod and changing the overall length of the rod. The fishing rod of the fishing rod devised in this way has a fitting female portion on the inner peripheral surface of the tip side end, and this fitting female portion is on the tip side end portion and the tip side peripheral surface of the former upper rod, respectively. It is designed to fit. And in the state where the former upper collar is pulled out to the tip side (hereinafter referred to as “stretched state”), the fitting female portion of the former collar is engaged with the outer peripheral surface of the former end of the former upper collar, In the state in which the is inserted into the base rod (hereinafter referred to as “stored state”), the fitting female portion of the base rod is fitted with the peripheral surface on the tip side of the top rod.
[0004]
In this way, the main rod and the upper rod can be connected and fixed to each other in either the “stretched state” or the “stored state”, and the length of the entire rod can be changed according to the situation. You will be able to fish.
[0005]
[Problems to be solved by the invention]
In the type of fishing rod in which the overall length of the fishing rod can be adjusted by the mutual relationship between the main rod and the former rod, the inner diameter of the fitting female portion of the former rod and the upper rod are improved in order to improve the mutual fitting force. It is set so that the outer diameter of the is exactly the same. For this reason, the marshal behaves like a cylinder of the piston, and the air resistance when pulling out or storing the marshal bar from the marshal increases, and the smooth entry / exit of the marshal bar can be hindered. is there.
[0006]
The piston phenomenon between the marshal and the upper arm may induce the suction of water and dust from the gap between the bottom plugs attached to the end of the armor. An unpleasant sound may be generated when the upper arm is taken in and out.
[0007]
An object of the present invention is to provide a fishing rod in which the length of the entire fishing rod can be easily adjusted by allowing the upper rod to be smoothly inserted and removed.
[0008]
[Means for Solving the Problems]
The fishing rod of the invention 1 is a fishing rod used for fishing, and has a large-diameter housing having a fitting female portion on the inner peripheral surface of the tip end portion and a bottom plug attached to the proximal end portion, and a large-diameter rod It is a housing connected to the tip side of the head in a swinging manner, and is formed on the outer peripheral surface of the first fitting male portion and the heel side end portion that is formed on the outer peripheral surface of the tip side and can be fitted to the fitting female portion. A small-diameter housing having a second fitting male portion that can be fitted to the female portion and having a through-hole formed in the peripheral surface of the first fitting male portion, and an inner periphery of the base-side end of the large-diameter housing And a fitting member that can be fitted to the second fitting male part of the small-diameter housing. The through-hole serves as an entrance through which air flows between the large-diameter housing and the outside through the small-diameter housing when the small-diameter housing is taken in and out of the large-diameter housing.
[0009]
In this fishing rod, in the large-diameter frame and the small-diameter frame, a state in which the small-diameter frame is pulled out toward the tip of the large-diameter frame (stretched state) and a state in which the small-diameter frame is stored in the large-diameter frame ( It is possible to adjust the overall length of the fishing rod by fitting and fixing each other. Specifically, in the extended state, the small-diameter housing is pulled out toward the tip of the large-diameter housing, and the second fitting male portion of the small-diameter housing is fitted to the fitting female portion of the large-diameter housing. On the other hand, in the storage state, the small-diameter housing is housed inside the large-diameter housing, the first fitting male portion of the small-diameter housing is fitted into the fitting female portion of the large-diameter housing, The fitting member is fitted to the second fitting male part of the small diameter casing.
[0010]
In this small-diameter housing, a first fitting male portion and a second fitting male portion are formed, and their diameters are set precisely in order to match the fitting female portion of the large-diameter housing. Therefore, when the large-diameter housing is taken in and out, there is a possibility that the large-diameter housing acts as a piston and the small-diameter housing acts as a cylinder, thereby hindering the entry and exit of air. Therefore, the through hole of the small-diameter casing serves as an air passage, and allows air to enter and exit from the large-diameter casing such as a piston through the inside of the small-diameter casing, thereby facilitating the operation. As a result, water and dust are not sucked from the gap between the bottom plugs of the large-diameter casing like a piston, and no unpleasant sound is generated.
[0011]
Moreover, since the through-hole is formed in the 1st fitting male part surrounding surface of a small diameter housing, it leads also to preventing adhering at the time of a 1st fitting male part fitting to a fitting female part.
[0012]
The fishing rod of the invention 2 is a fishing rod used for fishing, and has a large-diameter housing having a fitting female portion on the inner peripheral surface of the tip end portion and a bottom plug attached to the proximal end portion, and a large-diameter rod. It is a housing connected to the tip side of the head in a swinging manner, and is formed on the outer peripheral surface of the first fitting male portion and the heel side end portion that is formed on the outer peripheral surface of the tip side and can be fitted to the fitting female portion. A small-diameter housing having a second fitting male portion that can be fitted to the female portion, and having a through hole formed in a peripheral surface on the tip side of the first fitting male portion, and a base side of the large-diameter housing A second fitting male part having a small-diameter housing disposed on the inner periphery of the end part and a fitting member capable of being fitted; The through-hole serves as an entrance through which air flows between the large-diameter housing and the outside through the small-diameter housing when the small-diameter housing is taken in and out of the large-diameter housing.
[0013]
In this fishing rod, a first fitting male part and a second fitting male part are formed in a small-diameter rod body, and their diameters are set precisely in order to match the fitting female portion of the large-diameter rod body. Therefore, when the large-diameter housing is taken in and out, there is a possibility that the large-diameter housing acts as a piston and the small-diameter housing acts as a cylinder, thereby hindering the entry and exit of air. Therefore, the through hole of the small-diameter casing serves as an air passage, and allows air to enter and exit from the large-diameter casing such as a piston through the inside of the small-diameter casing, thereby facilitating the operation. As a result, water and dust are not sucked from the gap between the bottom plugs of the large-diameter casing like a piston, and no unpleasant sound is generated.
[0014]
Moreover, since the through hole is formed in the peripheral surface on the tip side of the first fitting male part, the through hole is not always covered with the large-diameter frame, and air enters and exits from the outside of the fishing rod to the large-diameter frame. Will always be smooth.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0016]
[Overall structure of fishing rod]
As shown in FIG. 1, a fishing rod that employs an embodiment of the present invention is connected to a harpoon 1, a former harpoon 2 that is coupled to the tip of the harpoon 1, and a harbinger side of the former harpoon 2. It has a middle cocoon 3 and a point cocoon 4 connected to the point side of the middle cocoon 3. These base rods 1 to 4 are tapered cylindrical members formed from prepregs in which carbon fibers or glass fibers are impregnated with a synthetic resin. Then, the upper heel 2 to the tip heel 4 are sequentially inserted into and removed from the pod on the heel side from the tip side, and are connected in a so-called swing-out manner. Note that the number of rods is set as appropriate depending on the length of the entire fishing rod required, and is not limited to four as described above, and any number can be used.
[0017]
The main rod 1 has a reel sheet 5 formed on the outer peripheral surface to which a reel (not shown) can be detachably attached, and a tail plug 10 is detachably attached to the end portion on the heel side. Further, slide guides 6 can be fixed to arbitrary locations on the peripheral surfaces of the respective casings and are slidably mounted on the peripheral surface of the casing. Are connected. Then, the fishing line from the reel is sequentially guided by the slide guide 6 and guided to the top guide 7.
[0018]
[Structure of Genroku 1 and Motogami 2]
In this through-hole, the upper arm 2 and the main shaft 1 can be fixed to each other in both the extended state and the stored state. Hereinafter, the structures of the yuan 1 and the motogami 2 are shown in detail.
[0019]
As shown in FIG. 2, the base rod 1 is a cylindrical body with a slightly tapered taper, and the base end portion is partially enlarged in a trumpet shape. Further, the inner peripheral surface of the tip side end portion is a fitting female portion that is fitted to the former upper collar 2 described later. A female screw member 11 and a short cylindrical fitting member 12 disposed adjacent to the female screw member 11 and inside the tip side are inserted into the inner diameter end portion of the flange having the increased diameter. It is fixed. The female screw member 11 is a substantially short cylindrical member having a thread formed on the inner peripheral surface, and the bottom plug 10 is detachably attached thereto.
[0020]
The fitting member 12 is formed of a synthetic resin or the like, and has a substantially short cylindrical main body portion and a plurality of protruding portions that protrude radially inward on the inner peripheral surface of the main body portion. A plurality of protrusions are formed at intervals in the circumferential direction of the main body, and are protrusions extending in the radial direction and extending in the axial direction, and are formed integrally with the main body. This protrusion is prepared so that its inner diameter matches a second fitting male part of the former upper collar 2 described later, and the former upper collar 2 is fitted in a state where it is inserted from the tip side. You may chamfer the tip side edge part of each protrusion part.
[0021]
The former upper collar 2 is also a cylindrical body with a tapered taper, like the former collar 1. A part of the outer peripheral surface of the heel side end portion and the outer peripheral surface of the tip side is formed with a slightly larger diameter than the other portions, and the outer peripheral surface of the tip side is the first fitting male part 2a and the heel side, respectively. The outer peripheral surface is the second fitting male part 2b. These fitting male parts may be formed by, for example, partially stacking an extra prepreg material or setting the diameter so as to partially increase the diameter during surface processing after housing molding. Formed. The outer diameters of both the fitting male parts are set so as to match the inner diameter of the fitting female part and the inner diameter of the fitting member 12 described above.
[0022]
A plurality of through holes 20 are formed in the first fitting male part 2a, which is a fitting part on the tip side of the former upper collar 2, on the circumferential surface thereof at intervals in the circumferential direction. The size of the through hole 20 can be arbitrarily set. In addition, providing the through hole 20 on the fitting male part 2a in this way is also preferable from the viewpoint of the strength of the housing. That is, generally, the auxiliary male prepreg material or the like is often wound around the fitting male part 2a in order to increase the diameter. By providing the through hole 20 in such a laminated portion of the auxiliary prepreg material, the strength is increased. Can be prevented as much as possible.
[0023]
In a through rod having such a structure, when fishing, the rods are sequentially pulled out toward the tip, and the rods are fitted together in a swing-out manner and used as a single rod. Further, at the time of storage, the attachment of each casing is released, and the tip-side casing is sequentially stored in the casing on the base side to make it compact. Furthermore, in the former fence 1 and the former fence 2, not only the state in which the former upper 2 is pulled out from the former fence 1 (stretched state) but also the state in which it is housed (stored state) is fitted to each other. It is possible to fish while adjusting the overall length of the fishing rod.
[0024]
That is, in the stretched state in which the former upper rod 2 is pulled out to the tip side of the former rod 1, the second fitting male part 2b of the former upper rod 2 is the tip side of the former rod 1 like a normal fishing rod. It fits and is fixed with the fitting female part of an inner peripheral surface (refer FIG. 3). On the other hand, in the stowed state in which the former upper collar 2 is inserted into the former collar 1, the first fitting male part 2a of the former upper collar 2 is fitted with the fitting female part of the former collar 1, and the second fitting male part is fitted. The portion 2b is inserted and fitted into the fitting member 12 (see FIG. 2).
[0025]
At the time of the entry / exit of the former upper cage 2 into / from the former cage 1, the through hole 20 of the former upper cage 2 serves as an air inlet / outlet to the inside of the former cage 1 through the former upper cage 2, thereby Smoothly prevent the former piston 1 from becoming a sealed piston. Such prevention of sealing piston also leads to prevention of generation of unpleasant sound when the original upper cage 2 is put in and out, and intrusion of water and dust from the gap between the main rod 1 and the bottom plug 10. In addition, the through hole 20 on the first fitting male part 2a reduces the contact area between the first fitting male part 2a and the fitting female part, and also prevents both from sticking.
[0026]
Further, by adopting such a structure, it is not necessary to provide an air hole in the conventional butt plug 10, and entry of water or the like from such an air hole can be prevented.
[0027]
[Other Embodiments]
(A) As shown in FIG. 4, the through hole 30 formed in the upper collar 2 may be formed not on the peripheral surface of the first fitting male part 2 a but on the tip side. In this case, the through hole 30 is always exposed to the outside without being accommodated in the main fence 1, and air can enter and exit from the main fence 1 more smoothly. Although the position where the through hole 30 is formed is not particularly limited, a position as close to the first fitting male part 2a as possible is preferable for the smooth supply of air to the main shaft 1, for example, the first fitting It is preferable to provide it within a range of about 200 mm in the axial direction from the joint portion 2a. In FIG. 3, only one through hole 30 is formed, but a plurality of through holes may be formed.
(B) In the said embodiment, although the fitting member is separately arrange | positioned at the heel side edge part of the main bar 1, in addition to using such another part, the inner periphery of the heel side of the main bar 1 It is also possible to use the surface itself as a fitting member.
(C) In the case of an external thread as in the above-described embodiment, the pointed collar is often made of a solid solid material. In the case of having such a solid spike, a pistoning phenomenon is particularly likely to occur, which is preferable for applying the present invention.
(D) It should be noted that the present invention can be applied not only to the external thread, but also to the internal thread.
[0028]
